Application led September 30, 1925. Serial No.v59,643.

The present invention relates to furnace construction and aims to provide novel means whereby a perfect combustion of the fuel will be maintained, eliminating to a de- 5 grec, the usual gases and smoke.

An important object of the invention is to supply air to the iirebox, the air being forced into the furnace in such a way as to become prcheatedpto the end that when the air conl tacts with the smoke and gases, the air will mingle therewith to dissipate the smoke and gases.

A further object of the invention is to provide means whereby the air will be fed even-` ly to the firebox to insure against cooling the fire bed.

lVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combi- !0 nation and arrangement of parts and in the details of construction hereinafter' described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a longitudinal sectional view through a furnace constructed in accordance 30 with the invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Referring to the drawings in detail, the furnace is of the usual construction and includes a irebox 5, grate 6, ash pit 7 boiler 8 and fire tubes 9 forming a part of the boiler.

Positioned above the iirebox and separated therefrom by means of wall 10 is an air chamber 11 which is fed with air through the pipe 12 that has connection with a suitable blower not shown, whereby air may be forced into the air chamber 11.

The wall 13 separates the air chamber 11 from the irebox 5. Pipes 14 which are carried by the wall 13 establish communication between the lirebox and air chamber 11 so that air passing into the air chamber 11 may pass downwardly into the iirebox through the pipes 14.

Arranged within the air chamber and supported by the door 15 are columns of pipes 16 which vary in size as shown by Figure 1 of the drawings, the pipes being supported by means of the band 17 that surrounds the pipes.

Air is regulated by the head 18 which is supported by the rod 19 that has a right angled extremity 20 passing through the pipe 12, the rod being constructed to move towards and away from the pipe 12 to vary the distance between the head and pipe to adjust the opening through which air passes to the air chamber.

From the foregoing it will be obvious that due to this construction, air forced into the air chamber 11 will strike the head 18 which is flared to the end that the air will be evenly distributed throughout the entire air chamber, and passed through the pipes 16 which evenly distribute the air throughout the areas of the pipes 14, to the end that the air will become preheated before it mingles with the smoke and gases of the iirebox.

The air which has been forced into the lireboX becomes heated and mingles with the smoke and gases causing the smoke and gases to be consumed.

The heat from the fire passes to the rear end of the furnace, from where it passes through the lire tubes 9, feeding the water contained in the boiler 8 from where the products of combustion pass through the smokestack 21 to the atmosphere.

I claim 1. In a device of the character described, a furnace including a rebox, an air chamber arranged within the fireboX, and supported adjacent to the forward end thereof, a plurality of vertical tubes within the air chamber, and arranged in spaced relation with the bottom of the air chamber, pipes extending through the body of the air chamber and establishing communication between the firebox and air chamber, and means for directing an air blast to the air chamber to feed the Firebox.

2. In a device of the character described, a furnace including al firebox, an air chamber arranged within the fireboX and disposed adjacent to the forward end thereof, said air chamber being in communication with Jthe reboX, a door for closing the forward portion of the air chamber, a supporting band secured to the door and extending into the air chamber, a plurality of pipes supported by the supporting band, said pipes having their upper and lower ends held in spaced relation with the walls of the air chamber, a pipe for directing a blast of air to the air chamber, and means for regulating the passage of air to the air chamber.

3. In a device 0f the character described, a furnace including a rebox, an air chamber within the ireboX and arranged adjacent to the forward end thereof, pipes for establishing communication between the air chamber and firebox, a plurality of pipes of Various sizes positioned Within the air chamber. means for directing a blast of air to the aix' 10 chamber, and means for regulating the passage of air to the air chamber.

In testimony that I claim the foregoing` as my own, have hereto a-flixed my signature.
